Questions tagged [kdf]

A KDF is a Key Derivation Function. A KDF is used within the field of cryptography to generate one or more keys from a seed value. This seed value could be a password or the secret generated by a Diffie Hellman key derivation function. Well known KDF's are crypt, bcrypt, scrypt, PBKDF2 and HKDF. The Password Based Key Derivation Functions are commonly used to securely "hash" a password using an iteration count and a salt.

Decrypt Message using secp384r1 ECC algorithm and KDFX963

I'm trying to decrypt a message using Elliptic Curve Cryptograph ECDiffieHellman using KDFX963 as a key derivation function (KDF) (defined in ANSI-X9.63-KDF http://www.secg.org/sec1-v2.pdf) But I'm struggling to get this done. I pretty much need a…
